Chess clocks are used to ensure fair play and to prevent time-wasting by the players. The app allows players to set a specific amount of time for each player's turn, and the clock will countdown the time for each player.
When a player makes a move, they press a button that stops their clock and starts their opponent's clock. The app also provides additional features such as the ability to customize the time settings, add increment time for each move, and keep track of the number of moves played.
A chess clock app is a handy tool for chess players to improve their skills and track their progress.
